Abstract: There is disclosed a sensor system for determining a fluid level comprising a first sensor comprising a contact sensor a second sensor comprising a conductive sensor and a transducer configured to determine a water level based upon pressure placed on the transducer. There is also a microprocessor in communication with the first sensor, the second sensor and the transducer, the microprocessor configured to determine from at least one of the first sensor, the second sensor and the transducer, a fluid level in a container. In one embodiment the system further comprises a memory configured to feed values to the microprocessor, wherein the values comprise at least one of a high-level fluid value and a low level fluid value. In one embodiment the microprocessor is configured to read pressure levels from the transducer wherein the pressure level of the transducer is configured to estimate a fluid level in a container.
